Abstract

The invention discloses a high-voltage pulse deburring device which is composed of a pulse ignition and DC detection power supply, a low-voltage pulse enabling power supply and an adjustment, control and protection display system. The pulse ignition and DC detection power supply comprises a high-voltage small-energy pulse ignition circuit. The low-voltage output end of the pulse ignition and DC detection power supply is electrically connected with one end of a vacuum pipe. A pulse ignition terminal or a DC detection terminal of the pulse ignition and DC detection power supply is electrically connected with the other end of the vacuum pipe. The low-voltage pulse enabling power supply comprises a low-voltage pulse charging power supply and a pulse forming network. The adjustment, control and protection display system is electrically connected with the pulse ignition and DC detection power supply and the low-voltage pulse charging power supply through wires. By means of the high-voltage pulse deburring device, burrs in a device are found through small-energy high-voltage pulses, ignition points are formed, then preset low-voltage large-current pulses are automatically output to fuse the burrs, and the aim of removing burrs in a low-energy-consumption and high-efficiency mode is effectively achieved.

Description

technical field [0001] The invention relates to a high-voltage deburring device, in particular to a high-voltage pulse deburring device. Background technique [0002] High-voltage deburring is an important process in the manufacturing process of electric vacuum devices. By applying high voltage between different electrodes of the device, the discharge phenomenon occurs under high voltage, so as to remove various tiny burrs or impurities and dirt inside the device, and eliminate discharge leakage current and sparking under the rated voltage between electrodes Breakdown defects ensure the rated withstand voltage strength between the electrodes of the device, so that the device can obtain good, stable and reliable working performance. [0003] At present, the electric vacuum industry generally uses AC high voltage or DC high voltage deburring process. During the deburring period, high voltage needs to be applied between the two poles of the device. When the burr between the e...
